Answer:
0.25 or 25% probability
Step-by-step explanation:
The lower limit in this question = a
The upper limit = b
P(X<=x) = x-a/b-a
a = 4
b = 8
The question says it is uniformly distributed between 4 minutes and 8 minutes
Probability that it takes her more than 7 minutes to wait for the bus
P(X<=7) + P(X>7)= 1
We are to get P(X>7)
= 1 - (7-4/8-4)
= 1-3/4
= 1-0.75
= 0.25
= 25% probability it takes her more than 7 minutes to wait
You randomly choose one of the following numbers shown. Find the probability the event can occur choosing a number greater than 4. (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11)
======================================================
Explanation:
The event space is the set of outcomes we want to happen.
The event space is {5, 6, 7, 8, 9, 10, 11} which consists of getting a value greater than 4. There are 7 items in this event space. Let A = 7.
The sample space consists of all possible outcomes. The sample space is {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} and there are 11 items in the sample space. Let B = 11.
Divide the values of A and B to get the answer we're after
A/B = 7/11
This is the probability of selecting a value greater than 4.

1. How did you compute sums of dollar amounts that were not whole numbers? For example,
how did you compute the sum of $5.89 and $1.45? Use this example to explain your strategy.
Your answer
Answer:
Computing the sum of $5.89 and $1.45 we get: $7.34
Step-by-step explanation:
We need to explain, how can we compute the sum of $5.89 and $1.45?
Computing the sums of dollar amounts is same as computing the sum of simple decimal expressions. Each value will be added to its corresponding values and we will get the answer.
Computing the sum of $5.89 and $1.45
[tex]\:\:\:\:\:\$ \:\:5.89\\+\$ \:\:1.45\\------\\\:\:\:\:\:\$ \:\:7.34[/tex]
So, we will start adding from right side, 9 will be added with 5 and we get 14, 1 will be given carry and 8 will be added by 4 and add the carry we get 13, 1 will be given carry and 1 will be added by 5 and add the carry we get 7
So, Computing the sum of $5.89 and $1.45 we get: $7.34

Find the total surface area of the prism.
7 ft
8 ft
5 ft
5 ft
Answer:
The total surface area of triangular prism
A = 232 foot²
Step-by-step explanation:
Explanation:-
Given bases of prism 5 f t , 5 f t , 7 f t
The perimeter of the sum of the bases
P = 7 + 5 +5 = 17 f t
Lateral surface area =perimeter X height
= 1 7 × 8
= 136 f t²
Base area of the triangular prism = [tex]\frac{1}{2} h ( b_{1} + b_{2} ) = \frac{1}{2} 8 ( 5 +7) =48[/tex]
The total surface area of triangular prism
[tex]A = p h + 2 Base Area[/tex]
[tex]A = p h + 2 Base Area = 136 + 2 ( 4 8 ) = 232[/tex]
The total surface area of triangular prism
A = 232 foot²

This is the last question that I am stuck on. It's the only one that I got wrong.
Answer:
m∠3 = 143°
Step-by-step explanation:
m∠1 = 53°
m∠2 = 180 - (90 + 53) = 37°
m∠3 = 180 - 37 = 143°
Answer:
143
Step-by-step explanation:
solution:
angle 1 = 53°
angle D = 90°
angle 3 = angle 1+ angle D [sum of two]
= 53°+90° [interior angle is equal ]
=143° [to an exterior angle]
A contractor buys 16 yd of nylon carpet and 22 yd of wool carpet for $1902. A second purchase, at the same prices, includes 20 yd of nylon carpet and 21 yd of wool carpet for $2033. Find the cost per yard of the wool carpet.
Answer:
$53
Step-by-step explanation:
Given that, two type of clothes nylon and wool carpet.
Let the price of one yard of nylon carpet = $[tex]x[/tex]
Let the price of one yard of wool carpet = $[tex]y[/tex]
Price for 16 yd of nylon carpet and 22 yd of wool carpet = $1902
Price for 20 yd of nylon carpet and 21 yd of wool carpet = $2033
Writing equations as per given statement:
[tex]16x+22y=1902 ...... (1)\\20x+21y=2033 ...... (2)[/tex]
Here, we have to find the value of [tex]y[/tex].
By equation (1), we get:
[tex]16x = 1902 - 22y \\\Rightarrow x = \dfrac{1}{16}(1902-22y) ..... (3)[/tex]
Putting the value from equation (3) to equation (2):
[tex]20 (\dfrac{1}{16}(1902-22y) ) + 21y =2033\\\Rightarrow 9510-110y + 84y = 8132\\\Rightarrow 26y=1378\\\Rightarrow \bold{y = 53}[/tex]
Therefore, the cost per yard for the wool carpet is $53.

The rate of change of traveling of the car is 63 miles every 1 hour.
Rate of changeA
Distance = 252 miles
Time = 4 hours
Average speed = Distance / time= 252 / 4
= 63 miles per hour
B
Distance = 378 miles
Time = 6 hours
Average speed = Distance / time= 378 / 6
= 63 miles per hour
C
Distance = 504 miles
Time = 8 hours
Average speed = Distance / time=504 / 8
= 63 miles per hour
D
Distance = 630 miles
Time = 10 hours
Average speed = Distance / time= 630/10
= 63 miles per hour
Therefore, the rate of change of traveling of the car is 63 miles every 1 hour

Question 1 (0.5 points)
Given a = 31, A = 84 degrees, and b = 20, use the Law of Sines to solve for B. Round
your answer to the nearest degree, and enter the number only. Note: The figure is
not drawn to scale.
Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
A = 84a = 31B = ?b = 20Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
